Hello Guys ,


What do you think would be the most effective , quick and most importantly cost-effective way to remove the
labels and glue adhesive from the common polycarbonate 5 gallon - 20 litre Water Jars.

Consider Sulphuric acid , please suggest the concentration or a specific type / alternate.

Try IPA

Try a solvent, MEK or Acetone.  They also make something called "vinyl off".  That stuff seemed to work real well.

MEK and acetone will attack/dissolve polycarbonate. Alcohols are better choice.

Goo-Gone is the best commercial product that I know of. It readily dissolves just about anything sticky or greasy. I've also used common naptha lighter fluid. Not only does it remove the stickers, but it also gets rid of the sticky residue and polishes up your jug a little bit. Another option is to just use plain hot tap water. My tap water usually runs around 110°F, so it won't melt the plastic. Run hot water over the surface, peel off the stickers, then scrub the residue off with a plastic scouring pad (don't use metal, it'll scratch). It's not the quickest method, but it will do the job, plus it's extremely cheap.

Motocross guys(aka me 5 years ago) used a product to remove graphics called "sticker off".  Its available at motorcycle shops and online.  SO far I have never used anything more effective.  DOn't know how many you are doing, it may not fit into the cost effective part of your equation.  A heat gun will also make quick work of stickers and usually the adhesive will come off with the sticker, but its not as "sexy" a solution as using exotic chemicals.

Heat guns also tend to melt plastic if pointed at them for too long. PET is probably the plastic used in the water jugs, which melts at around 250 degrees celsius. Maybe a very low heat heat gun would work, but prolonged exposure would probably still melt it.

I rekon Typhoon has the best bet here  -  try wiping with IPA.
